The Wi-Fi MCU plays a big role in moving the IoT forward by combining a processor, Wi-Fi transceiver, I/O, and other functions in a single SoC. They perform not just Wi-Fi connectivity but surprising levels of MCU performance, extensive security measures, and considerable amounts of IO.

While it might not get lots of media attention, the Wi-Fi microcontroller (MCU) plays a big role in moving the Internet of Things (IoT) forward by combining a processor, Wi-Fi transceiver, I/O, and other functions in a single system on chip (SoC). And even though they may appear to be comparatively simple devices, there is a lot going on under the hood, as they perform not just Wi-Fi connectivity but surprising levels of MCU performance, extensive security measures, and considerable amounts of IO. So, you need to consider them all to minimize risk. If you don’t, changing the device later requires redesigning all the software and the configuration of the accompanying circuit…
